Synergistic Red Fuse ...

I installed a SR RED Quantum fuse in my ARC REF-3 preamp a few days ago, replacing an older high end fuse. Uhh ... for a hundred bucks, this little baby is well worth the cost. There was an immediate improvement upon installation, but now that its broken in (yes, no kidding), its quite remarkable. A tightening of the focus, a more solid image, and most important of all for my tastes, a deeper appreciation for the organic sound of the instruments. Damn! ... cellos sound great! Much improved attack on pianos. More humanistic on vocals. Bowed bass goes down forever. Next move? .... I'm doing the entire system with these fuses. One at a time though just to gauge the improvement in each piece of equipment. The REF-75se comes next. I'll report the results as the progression takes place. Stay tuned ...

Any comments from anyone else who has tried these fuses?

What it is the difference between slow or fast blown fuse? Does have ant impact in sound?

Follow the owner's manual for your specific equipment. It will call for either a slow or fast blow fuse of one particular value.

I have Linn Numerik DAC, I have checked the manual, it mention about BS1362 5A fuse, it is not specified if it should be fast or slow. Also, I don't understand why it needs 5A fuse, it is a DAC, not an amplifier.
Thanks

OK, Meanwhile I found folowing answer which seems to be logical and could be usefull if there is no mention in manual. Anyway, if there is something wrong or to be added, please do, I would like to clarify this aspect and order some fuses next week. 

" The answer to this depends on the application. The main purpose of a fuse, in any application, is to prevent a fire. If the fuse is in the loudspeaker circuit, ie, in series with the loudspeaker as a load, then it needs to tolerate occasional overloads, but open on continued overload - so, medium slow blow. If the fuse is in series with a transistorised power supply's pass transistor, then it needs to be a very fast blow. If the fuse is in the mains input lead before any power supply unit, then it needs to sustain the start-up current required to charge the main filter capacitors - so, slow blow. In summary, look at the application."

Fuse in Linn Numerik DAC it is located next to power in socket, so I assume that it is before any transformer power supply, so it should be slow blow?

Thanks
